mpnovna'mm 11v G AIN-Dramas The Schedule zefen'edto in these Letters Patent and part of the same;

To all whom it anal concern:

Be it known that 'LMARTIN HAYDEN, of Dow'- agiac, in the county of Gass,'and State of Michigan, have invented anew and useful Improvement in Grain-Drills; and I do herebydeclare that the following is a fnll, clear, and exact description of the construction and operation of the'same, reference being had to the annexed drawings making a part of and the drill-teeth'are so arranged as to be entirely under the control of the operator, who can guide them in line, though the team may accidentally-or purposely be driven out of line.

II! the accompanying drawings- I A represents a frame, which may be constructed in any suitable known form, and is provided with the carrying wheels'B.

' A transverse section of the hopper and seed-box is shown at D and D. Said hopper and seed-box are attached to the frame A in the-usual manner, (not shown in'the drawings.)

' E represents the bottom, provided with theopenings a afor. each drill, which are adjustable longitudinally by means of the lever E, which actuates the slide-' bar (1;

A vibrating bar, G,.is suspended in thc. hopper by means of the pendent arms H H, which are pivoted to the upper and inner side of the hopper, so as to allow the bar-G to swing endwise.

1 represents agitators, slotted to receive the screw. by which they are attached to the bar G, making them adjustable vertically, bywhich means -thedistributiug device is in part regulated.

j represents a rock-shaft, passing through and supported by the sides'of the hopper and seed-box, and

provided with three arm's,"one of which is seen at It, and is attached to the crank-arm of the pinion M, by

means of the connecting-rod L. I

N is another-arm of said rock-shaft,'and is Slottedat the lo\ver end,-to receive the pivot 3 in the vibrating bar not the seed-box I). Said harissuspended by the pendent arms, P. vA 'third'arni of said rock-shaft,

'lar rack 16.,

lever is held inany desired position by means .of a notched post, as seen at T, with which the handle of "said lever engages by its natural tension, and is'disengagedtby springing the handle sidewise.-' v

u represents funnel-shaped spouts, attached to the hopper bottom,one side of which is elongated and slotted, to receive the pipe 0;, and is fastened at the? lower end to the-bar W. This bar serves asa snpport to the frame and arest for'the upper ends of thepipes '0. These pipes havaportion-of their uppersurface cut away, to receive the grainfrom the spout u-. The lower ends are pivoted to the hollow standards 0.

An oscillating bar, 2:, is bolted'to the under side of I .the rear end of the tongue y at its ,center, by.means of a crotched draft-plate, z, which -prevents said bar from canting. Guard-irons, as seen atom, are attached to the under side of the frameA, for the purpose of supporting the ends of bar x. v

To-this bar are pivoted the forked draft-bars e, and to each end is attached an ironro'd marked 4,-connecting with the short arms of the beutfoot-levers 5. The long arms of .these levers form stirrups for the feet of the operator, marked 6, hy means of which the bar a: is

made to oscillate, cansing a lateral movement of the drill-teeth.

Each end of 'thebar 8 is hinged to the frame A by means. of the ear-s9; attached to one corner. From the opposite corner project the slotted brackets 10,

through which the suspension-rods 11 work. These rods are provided'with hooks at theupper end, to prevent them from drawing down through the slots, and the lower ends are pivotedto-the draft bar (2, carrying ,thecoiled springs'lfl, The object of these springs is to cause penetration of hard ground where the simple weight of the drili-tooth'wouldhc insufficient. v

V Thelower corner-ofbar'8is provided with-the short arm 13, to the movable end ofwhich isqiivoted one end of the rod-l4; The other 'end of said rod is pivote'd to thecurved lever 15. The lower .cndvof this lever is pivoted to the center of, the stationary circu- .A-pin,,marked 12," projects from one side of -the,

lever-J5, and engages-with the teeth of said rack, and

is held in position .hy-thespring 18.

' The forkeddrait-bars'e are bent edgewise at the 'rear end, forming strong elbows that require no brac-.

. Oirculaz-gua ds, marked 20, are attached to the standards'O, than are made sharp in front,ifor the purpose ofcutting through or drawing over any-obstructions to the dlill-teeth.

A dm'vers seat (not shown in the drawings) is at tached to the rear part of the frame A, most convenient to the foot-1evers6. It will be seen that bymoving the lever 15, the drilL-teeth can be raised or lowered at will.

Having thus fully described my invention, any one skilled in the art can construct and operate it.

What I claim as-new; and desire to secure by Let-r ters Patent, is-

l. The rock-shaft j, having the arms K, N; and q, when arranged as set forth.

2. The slotted adjustable agitators I, with vibrating bar G, substantially as specified.

3.- The hinged bar marked 8, having the slotted brackets 10,:u-rn 13, rod 14, lever 15, and circular rack 16, when arranged as described.

d. The oscillating bar 2:, having the crotch-plate 2,

marked 20, all constructed'and operated substantially as set forth.

In testimony whereof I have hereunto set my hand this 12th day of July, 1869.
